Thank you for your feedback! Bionic uses MCT oil which generally doesn’t cause any pip. Me personally I like test e better and have had no pip issues using his test e.I’ll be honest, the Test Cyp250 kinda PIPs up and leaves a little welt. Nowhere near as bad like a Test Prop, but it can smart at 1ml. Just some feedback for yall. Still works great and I can always “feel” Test Cyp, so I know its good to go![]()
